![]() I've not gone deep into a rama before, but it's no more than 4 or 5 elements forming the anamorphot behind the pair of sphericals handling the focus diopter duties.Īs Andy has stated, it is certainly worth trying out the multi element century wide angle attachments with a helios 44 when on smaller sensors like the pocket since it is only at the edges where these attachments fall apart. ![]() In the same way the iscorama loves the helios 44, my drive for the wides has been this integration of a planar lens and a high quality wide attachment (which the iscorama effectively is, but only on the horizontal plane). It's the combination of slower speed and the fact that the wider lenses don't contain that magical double gauss lens prescription. is it the slower speed or other properties that don't make something like this appealing, Rich? They tend to not be as fast as the 58mm however: Since the Helios 44 is a copy of a Zeiss Biotar I would think wider Jena lenses would be in the ballpark. They have a built in point spread function that's been engineered out of modern glass that wants to simply pass light through as unaffected as possible (which exacerbates the bad mojo you get from fixed grid sampling in CCD and CMOS). You kinda roll the dice.Ī mathematician and human visual system specialist friend of mine has interesting things to say about Russian glass that syncs right up to what I think I recall Rich mentioning about the glass itself and micro diffusion properties.

Even with the Helios 44 there seems to be a palette of available looks based on era, manufacturer, etc. The Helios Prototype is an enlarged version of the Centurion flying wing that flew a series of test flights at Dryden in late 1998.

Even if the design itself is a carbon copy I would imagine the source or formula for the glass itself and coatings would make some kind of difference. So that is to the Jena 80mm as the Helios is to the Zeiss 58mm? Do you or have you had access to both? I'm curious how they compare, not that the real Jena are terribly expensive. ![]() You can buy the Russian KMZ copy of it the MC VOLNA 80MM F2.8 The P6 Zeiss lenses are very good, especially the 80mm Biometar mine is a 1964 version pre zebra with a plastic focusing ring and it is one of the sharpest lenses I own !! its a great lens with alot of character The DSO option sounds like a great alternative if nothing in the 28-35mm range pans out. I don't know if this is true for the entire family of Jena glass or just the longer end, or just folklore but the proof is in the pudding AFAIC with the 80mm Biometer. The earlier, larger, single-coated versions are going to have more "magic". Performance is reportedly about twice what the numbers would lead you to expect when paired with a smaller format camera.Īlso, it may be better to go for the "zebra" versions rather than the black painted or anodized "MC" version because I've read at least one reference that states the coatings on these later versions suffered from supply problems in communist DDR. ![]() Something to consider while looking at the Jena series is I've read steer towards the Pentacon 6 mount and not the M42 version. ![]()
